e portion of my device adapted t be ap As illustrated in Fig 1, t e device can be acplied to the rail which may b termed shoe, tuated longitudinally on the rail in either direcconsists of a substantially rectangular fram 4 tion- '40 in WhlCh transverse flanged rollers are jour- The frame l is applied to the rail as illustrated in F freely through the longitudinal portions of the adapted to run on the tread of the rail. The 45 frame I, and the threaded extremities of the pr0ViS n 0 t h p member 3 n e legs 4 carrying nuts 5 adapted to be held against spring 6 pe t device ac mm a the adjacent longitudinal portion of the frame self to variations in the width of the tread of the legs 4 and having their ends respectively mit adjustment of the member 3 in the frame. 50 leg extremities interiorly of the frame. (depicted in Fig. l as A), the sleeve [5 is rotated A depending stud 1 is provided on the base of by the knob i 6 in the required direction with the U-shaped member 3 exteriorly of the frame the result that the sleeve will move upwardly 55 and through the medium of the attached flanged plug II will compress the spring IS. The spring will now exert a downward pressure on the flanged plug 5 thereinto and causing the plunger to move down in the cylinder lil expelling the grease through the outlet 22, tube 23, passageway 2 and outlet 26, delivering the grease onto the side of the ra'l tread in the form of a series of beads as the device is pushed along the rail.

When the spring 18 by elongating as above described ceases to exert the required pressure it is only necessary extent wherein the spring is again compressed and pressure exerted on the plug l1 and attached the apparatus is moved along the sleeve i5 is intermittently rotated to keep the spring It in compression and thus secure a continuous fiow of the greasecnto the rail.

A lubricator such as described above is particularly applicable for use on the high rail of tracks on curves.

What I claim as my invention is:

1. In a rail lubricator, in combination, a shoe adapted to be moved longitudinally on the tread portion of the rail and comprising a frame including spaced side members, transverse rollers journalled between the side members of the frame and adapted to roll on the tread portion of the rail, a U-shaped member having its legs extending transversely and freely through the side members of the frame with the base of the U disposed exteriorly thereof, nuts threaded on the legs of the U-shaped member and engageable with the interior face of one of the frame side members, spiral springs on the legs of the U-shaped member having their ends engageable respectively with the nuts and with the opposite frame side 0 members, an element depending from the base of the U of the U-shaped member and engageable with one of the sides of the tread portion of the rail, an abutment on the frame engageable with the other side of the tread portion of the rail and including lubricant dispensing means for dispensing lubricant onto a side of the tread portion of the rail, and means for feeding lubricant to such lubricant dispensing means.

2. A rail lubricator as claimed in claim 1 wherein the lubricant dispensing element is incorporated in the abutment.

3. In a rail lubricator, in combination, a shoe adapted to be moved longitudinally on the tread portion of the rail and comprising a frame including spaced side members, transverse rollers journalled between the side members of the frame and adapted to roll on the tread portion of the rail, a U-shaped member having its legs extending transversely and freely through the side members of the frame with the base of the U disposed exteriorly thereof, nuts threaded on the legs of the U-shaped member and engageable with the to rotate the sleeve Hi a further interior face of one of the frame side members, spiral springs on the legs of the U-shaped member having their ends engageable respectively with the nuts and with the opposite frame side members, a depending roller rotatably mounted in the base of the U of the U-shaped member and engageable with one of the sides of the tread portion of the rail, an abutment on the frame engageable with the other side of the tread portion of the rail and having a lubricant passageway therethrough with its discharge end in the face of the abutment engaging the side of the tread portion of the rail, and means for feeding lubricant to the lubricant passageway in the abutment,

4. In a rail lubricator as claimed in claim 1, a member having itslower end transversely journalled between the side members of the frame, a lubricant cylinder mounted on the upper end of said member, means for connecting the lubricant cylinder with the lubricant dispensing element on the frame, and means for feeding the lubricant in the lubricant cylinder to the lubricant dispensing element.

5. In a rail lubricator, in combination, a shoe adapted to be moved longitudinally on the tread portion of a rail in either direction, a lubricant dispensing element on the shoe engageable with a side of the tread portion of the rail, a member transversely journalled at its lower end in shoe, a lubricant cylinder mounted on the upper end of such member, means for connecting the lubricant cylinder with the lubricant dispensing element on the lubricant in the lubricant cylinder to the lubricant dispensing element.

6. In a rail lubricator, in combination, a shoe adapted to be moved longitudinally on the tread portion of the rail and comprising a frame, spaced apart transverse rollers journalled in the frame, a depending abutment on the frame adapted to engage a side surface of the tread portion of the rail, a laterally adjustable depending element on the opposite side of the frame adapted to engage the opposite side surface of the tread portion of the rail to that which the abutment engages, and spring means on the frame co-operating with the depending element for causing the abutment to continually contact the side surface of the rail tread portion at all times irrespective of variations in the width of such tread portion.

7. A rail lubricator as claimed in claim 6 wherein a U-shaped member has its legs extending freely transversely base of the U-shaped member disposed exteriorly thereof and the depending element mounted on the base of the U-shaped member, and the spring means operatively mounted between the frame and the U-"haped member for causing the depending element to resiliently engage the side surface of the tread portion of the rail.
